We  also offer this Product with different specifications or size (Custom Solutions), in higher amounts (Bulk Inquiries) or under OEM Basis (OEM Partnerships).

Note: Prices may vary between countries, because additional cost may be applied due taxes, shipments or Custom fees.

• Convenient: recognition sites for EcoRI and NotI flanking the insertion site.
• Flexible: allows removing the desired insert DNA with other restriction digestion.
• Efficient: more than 600 white positive colonies expected under optimal conditions.
• Stable: without cloning bias due to transcription of toxic genes.
• Easy-to-use: eliminates screening of recombinants due to its low background (4%).
• Fast protocol: ligation time from 60 minutes to overnight.
• Compatible: with direct cloning of PCR products.
• Great versatility: compatible with any competent cell, primer design or particular proofreading DNA Polymerase.
• Cost avoidance: avoids primer phosphorylation.
• Risk-free: product covered by our Quality 100% Guarantee.

Includes for 20 rxn:

– 20 µL pSpark® TA Done (50 ng/µL)

– 20 µL T4 DNA Ligase (5U/Weiss)

– 200 µL T4 DNA Ligase Buffer (5x)

– 5 µL Insert Control 1 kb (20 ng/µL)

• Cloning of non-proofreading PCR fragments.
• Production of ssDNA.
• Blue/white screening for recombinants.
• In vitro transcription from T7/SP6 dual-opposed promoters.

• Functional test using a 600 pb PCR fragment.

• Recommendations: All pSpark® DNA cloning vectors are stable for at least 1 month at 4 °C and even at 20 – 25 °C for up to 2 days although storage temperatures above -20 °C are not recommended. In case of incident, such as a power failure, stored vectors should be tested with the supplied control insert before considering discarding it. However, please note that T4 DNA Ligase is extremely temperature-sensitive and storage temperatures above    -20 °C inactivates the enzyme.

• Shipped in: Gel Pack.
• Storage: -20 ºC (NON Frost-Free Freezer).
• Shelf Life: 24 months from the date of purchase, if it is properly stored.
